BOOK COVERING AND BINDING Specification of Letters Patent.

Patented Sept. 6, 1921.,

Application filed November 11 1919. Serial No. 337,159.

. To all whom it may concern:

Be it known that 1, CHARLES A. JunNcs'r,

' a citizen of the United States, and a resident of Croton Falls, in the county of Westchester and State of New York, haveinvented certain new and useful Improvements in Book Covering and Binding Machines.

The present invention relates to book covering binding machines or machines thatperform both of these functions and has for its main object the provision of means where I by books of widely different makeup may be bound 0r covered or both.

. cover feeding and gluing means:

Fig. 5 is a broken view in elevation looking in the direction of the arrow 5 of Fig. 4: Fig. 6 is a detail'sectional view on the line 6-6 of Fig. 2: I

Fig. 7 is a detail sectional view on the line 7-7 of Fig. 5: and

. Fig. -8 is a" sectional view showing one style of book produced by the machine.

Although the machine of the invention is adapted to act purely as a covering machine for, say, stitched or stapled books, the prod-.

not that it is more particularly desired to obtain is shown in Fig. 8. As theredisclosed, the signature group 1 is trimmed at the bottom or back, glue is applied and a strip 2,

of crash, or the like, and a. blank 3 ofcardboard, or ttge glued back, h of the signature group and the cardboard. A cover 4 is then glued on the cardboard blank after which the cover is broken.

As shown in Fig. 1, the machine as a whole may consist of a book conveyer 5 traveling in a horizontal orbit and having clamps 6. The construction of the conveyer. and the various instrumentalities that act on the Figure 1 is a more or less diagrammatic like, are pressed against the. e crash being between the back book, except those hereafter explained in detall, may be the same or substantially the .same as those shown in Patents Nos. 1,193,395

and 1,244,861. Preferably the book conveyer has a continuous advancing movement. Arranged along the path, of. the book conveyer are the various instrumentalities that act on the book here taking the form of a cuttmg mechanism 7 for cutting off the back of the book, a roughening device 8 .for rendering theback of the book more receptive to glue, a glue applying means 9, a crash and cardboard feed;1O, covering feeding means 11, glue applylng means 12 and a cover breaker 13.

As in the machines of Patents Nos. 1,193,- 395 and 1,244,861 it is desired to perform all the binding or covering operations, or

both, while the book is on the run although.

the features of the invention are not necessarily limited to a so-called continuous machine- In the production of a book such as is shown in Fig. 8, the signature group is trimmed and roughened and glue is applied to the back of the book. The crash and cardboard are now applied to the book, and the means for accomplishing it as here disclosed take the following form 14 is a hopper for cardboard blanks 3, and these blanks are delivered singly from the bottom of the hopper as by means of a slide 15 actuated by means of lever 16, pivoted at 17,

red 18, cam lever 19, pivoted at 20,'having cam roll 21 engaging cam, 22.

i 23 is a' cradle or frame consisting of side cheeks 24 connected by means of member 25, the latter being mounted on two cranks 26 rotated by means of shafts 27 that receive motion in some suitable way, as by means of sprocket wheels 79. Mounted on member 25 is a presser element 28 of a length equal to that of the back of the long est book that the machine is adapted to act .upon. The lower ends of cheeks 24 constitute means forsupporting a source of supply 29 of crash in web form. Cheeks 24 also carry a guide'roller 30 and a feed cylinder. 31, the latter of which may consist of a number of pulleys mounted on shaft 32. Coacting with cylinder 31 is a pressure roller 33. Cylinder 31 is rotated intermittently by means of pawl '34 and ratchet 35, said pawl being hung loosely on shaft 32 by means of cylinder are two knives 49 and 50 arranged substantially at right angles to each" other.

Knife 49. is relatively stationary but knife' 50'is mountedin holder 51 pivoted at 52 and normally held out of contact with 49 by means of spring 53. Both knives are carried by the cradle. ment surface 54 (Fig. 3) which, when brought in contact with stationary cam- 55 in the main frame-of the machine, acts to depress knife 50 and to sever a section from the crash webs The revolution of cranks 26 raises and lowers the cradle and also moves it longitudinallysubstantially in unison with the book conveyer when the cranks are passing through their upper arc of movement, the

- cradle carrying with it presser element 28 and the source of'supply of crash as well. as the crash feeding and severing elements.

- When-presser element 28- reaches the .level 1 occurring during the continued upward and forward movement of the cradle. Eventuabutment surface 54 strikes cam 55 and ofvslide. 15 on its up stroke, a cardboard "blank 3 is deposited on said presser element.

Afterthe blankis deposited on the presser element, pawl 34 and ratchet 35 feed a section of the web on top .of'the blank, this a thesection is severed from the web and the continued upward and forward movement .then presses the crash and blank against the glued back of the book. After this, the

' cradle returns and the operation is repeated onthe'n'ext book. v k

A cover is, nextapplied to the book and this is accomplished by means of cover feeding means 11 and coverbreaker 13. The

' icover feeding means here comprise chains 56, carrying the cover :over supporting guides 57,. andcover'drum 58. This cover drum may or may not roll the sheet'against theback oflthe book'as explained in Patent No. 1,193,395. In the form here disclosed the cover sheet is received in the bite of drum 58 and tapes 59, the latte1"- passing over .pulleys 60. Chains 56 run in grooves below .the surface of drum 58 as explained in said Patent No. 1 ,19 3,395 so as not tointerfere with the control of the cover sheet by drum 58v and: tapes 59. Adjacent the coverdrum is a lue pot 61 havin a glue roller 62 rotacarried in arms. 64 of vrockslfaift 65 and springs 66, acting'on the free end of arms Adj acentthe upper. side ofcylin-.

Holder 51 has an abutgluing the back of the book, and 'cover breaking mounted ons aft 63. Thisshaft is 64, normally urge glue roller 62 toward cover drum 58. ,A cam 67 rotating with cover drum shaft 68, acts against'roller 69,

carried by arm 70 on-rockshaft 65, to move glue roller 62 away from cover drum 58 in adtectbr consisting of a plurality of fingers extending" into grooves 72 of cover drum 58-and mounted on shaft 72 having at itsother end abutment member 73. When a sheet passes to the cover drum atthe proper t1me,-it will move detector fingers 71 out of grooves 72 and abutment'member 73 ,will be out of the pathof heel 74 of arm 64 and spring 66 will, therefore, be free to lift the glue roller into contact with the sheet carrying cover drum. If, however, no cover sheet is present at the proper time, spring 75 will retain detector 71 in grooves 72 and.

abutment member 73 will-be in'the path of heel 74 and spring 66 will be unable to lift the glue roller" 75 (see Fig.7) is a" scraper acting against glue roller 62 and mounted on arm 76 pivoted at 77 in the bearings of shaft'63. Arm 76 carries an adjusting screw 78 that comes against the stop formed by shaft 65. Bythis means, the thickness of 1 the interval between successive sheets. 71 is the-layer of glue on the gliie wheel is controlled.

-T-he cover sheet arriving at the cover drum is glued in .the center,,and is.v then pressed into contact with the cardboard blank on the back of the book. As previously explained, the eoverp'ressing maybe performed by the cover drum. After this thecover is broken by cover breaker 1'3.

\In some shops, the character of the makeuppf the books varies. For instance, when 'stitche'd books are run through the machine,

the binding means are rendered inoperative. Thus, in the machine of the present application, the instrumentalities 7, 8, 9.and 10 may be rendered ineperative and the machine may then be .run as a coverer by means .of the instrumentalities-11,12 and 13.
